FLOOR SURFAGER AND POLISHER Filed April 16, 1931 Patented Aug. 14, I934 My invention relates to floor surfacers and pol-" ishers of a simple character whereinea frameis formed'to support;- the operating-- parts-guidedlby an adjustable handle which may be -set' -withthe engaging end-at different heights. 2-

A feature resides in an inexpensive devi'ee'u'sed for surfacing or polishing floors and wherein-the action is positive with all'of the parts' easilyaccessible, The frame of the device includes si'd'e members across which a p1atform extends and upon this platform the -electric motoriwhich' is adapted to drive the surfacingimenlbei r whe'el is carried. This places the motor in position so' as to take advantage of the weight of the same in bearing against the polishing in -floor surfacing roll in its operation;- Bythis structure =-the:ma-*

chine or device may be made otherwise of a'light=' weight, making it easy to handle in'moving itover the floorinoperation. .v 3:: A feature residesuin 'a"-particularly formed frame, one side of which is'capableof lieing su-nle away from the end'of the roller carrying the-bearing in the outer free end of the same and thus permitting. a new roll to be quickly and. easily slipped intov place on the supportingzshaft which actsto steady the roll andcarry it true in=itsirotation supported by the bearings in the :forwardlendxof the frame. Suitable clutch meansareiprovided for-engaging the rollto carry-rit aboutrwith the supporting shaft;v -1-15" The extension of the: rollsupportingl'shaftnon one side of the 'frame permits thei driving. from themotor toxbe direct and'close to the rollgiwhile' the motoris "readily adjustable. on,.the. platform to. regulate" the tension in .theadrivingrbelt' or chain. The extension of: the roll supporting. shaft also permits the attachment of a fioorasurfacing member extending. to one side Y of Y the frame; ofthe machine so that. .the floormay. be; surfaced close to the wall, like as h'as not been accomplished heretofore in so simple and.- praetical a manner: insofar as I know. I f 5 By means of a suitable-shielding hood which is carried upon supporting p'inson the front end of the frame of the machine,--'the surfacing 'or p01 ishing roll is protected and shielded over fthe' top' and comparatively close to the floor engaging portion of the same. This hood may be quickly lifted off when it is desired.
